Rebirth 91, this time I want to be a doctor

Li Yan stood outside Teacher Qian's classroom for a while. Teacher Qian was teaching a small class and was in the middle of a lecture, so it was not easy to interrupt.I had no choice but to come back and say to the parents: "The teacher is giving a lecture. Can you and your child wait a little longer?"

The parents nodded helplessly.At this time, the boy looked through the answers at the back, and sure enough he chose bc, and said to Liu Xiaochuan: "Awesome, buddy, you solved this question after just two glances. Which school are you from?"

Li Yan quickly introduced: "This is our new teacher Liu. He is a college student from the Normal College. He teaches very well."

"So you are also a teacher here, no wonder you are so good." The boy said a little embarrassed, recognizing Liu Xiaochuan as a high school student.In fact, this is not his fault at all. Liu Xiaochuan is actually one year below him.

The parent said doubtfully: "Since Teacher Liu is good at teaching, why don't you arrange for him to give us a trial lesson?"

Li Yan explained: "Aren't you afraid that you think Teacher Liu is young? So we plan to arrange an experienced teacher for you."

The parent smiled and said: "Hey, what are you afraid of when you are young? When learning this thing, those who are masters come first. As long as the teaching is good and the children like to listen to the lessons, everything else is not important."

After hearing this, Liu Xiaochuan couldn't help but give her a big thumbs up in his heart, thinking that this aunt is really open-minded and has an extraordinary vision. You deserve to be rich!

Since the parents didn't mind, Li Yan quickly went to the principal's office to ask Wang Tongguang for instructions. Wang Tongguang naturally agreed and asked her to arrange for Liu Xiaochuan to give a trial lecture.

The boy's name was Xu Meng. He smiled and said to Liu Xiaochuan: "I'm sorry, teacher, I really thought you were just like me and came to make up lessons, so I called you buddy."

"It doesn't matter. There's actually not much difference in age between us. There's nothing wrong with calling us buddies. So, let me tell you about the question just now. What do you think?"

"Okay, I'm just curious, how did you do it so fast." Xu Meng looked curious.

"Actually, during the exam, not every question needs to be calculated, especially the multiple-choice questions. We have to learn to guess. You know? There are many techniques."

"Ah, rely on Meng?"

"First of all, you have to know it before you can get confused. Do you understand? For example, this question is multiple choice, right? It gives a lot of conditions, mainly describing the planet's revolution around the star. We can only calculate the mass of the central celestial body, because in the equation The mass of the planet will be reduced, so we cannot calculate it at all, so the calculation result of option a regarding the mass of the planet must be wrong, so we should rule it out first."

After a pause, Liu Xiaochuan continued: "Let's talk about option d. We need to calculate the rotation period of the planet. We don't even know whether the planet is rotating, so how to calculate the rotation period is impossible. Multiple choices exclude ad, so naturally That’s all left bc.”

Xu Meng nodded repeatedly, suddenly enlightened.

"Don't worry. During the exam, we did the questions like this, but now we are practicing to master the knowledge points, so we also have to calculate the bc option. The reason why the celestial body part is difficult is that it requires a lot of calculations. , mostly alphabetical operations, easy to make mistakes. To say it is simple, in fact, most of the questions only use one formula, and gravity acts as the centripetal force. "

After a pause, Liu Xiaochuan continued: "Although only this formula is used, the centripetal force must be written in different forms according to the purpose of calculation. Therefore, as long as you are good at circular kinematics and have strong mathematical calculation skills, the content of this chapter on celestial bodies is almost You don’t need to learn to master it.”

Next, under the guidance of Liu Xiaochuan, Xu Meng calculated the results of the BC option on scratch paper and felt quite accomplished.Liu Xiaochuan pointed out that Xu Meng's calculation level and calculation speed were relatively poor, and he needed to practice more, otherwise he would easily fail to answer the test papers during the college entrance examination.

Xu Meng had already written a big word "submit" in his heart.I highly approve of Teacher Xiao Liu.Xu's mother was also listening. Although she didn't understand, the young teacher seemed to be very good at teaching, which was evident by looking at her son's expression.

Li Yan struck while the iron was hot and asked Mrs. Xu if she wanted to set the course.Mother Xu didn't mess around, she paid the fee directly, and agreed to attend classes every day, starting today. After all, the senior year of high school started early, and her children had many gaps in their courses, so they had to start as soon as possible.

Li Yanxin said: "This is another big customer."

Next, Liu Xiaochuan told Xu Meng about Kepler's laws, the double star problem, etc., and led him to do some exercises. Xu Meng felt that he had gained a lot.

In the afternoon, the little girl Wu Han came to class as scheduled, and Liu Xiaochuan's work got off to a pretty good start.

At around two o'clock in the afternoon, Taoliju Restaurant had just finished lunch. Zhao Lijun did not play mahjong in the afternoon. He borrowed the boss's bicycle and inquired all the way to the Yuquan Street Police Station. When he looked up, he saw the big sign of Chunfeng Education next door. I went up to the second floor feeling anxious.

When Li Yan saw Zhao Lijun, she looked neither like a student nor a parent. Could it be that she was also here to apply for a job?But he didn't look like an intellectual at first glance, so he had to ask: "Um, comrade, who are you?"

"Does Liu Xiaochuan work here?"

"Yes, Mr. Ogawa is in class, who are you?"

Zhao Lijun breathed a sigh of relief. It seemed that his cousin really didn't lie to him. "Oh, I'm his cousin. I just came to see him. It's okay. I'm leaving."

Liu Xiaochuan had just finished class when he heard the conversation between Zhao Lijun and Li Yan. When he came outside, he saw his cousin standing at the door.

Zhao Lijun was the first to speak: "I was just passing by and came to see you."

Liu Xiaochuan knew in his heart that Zhao Lijun obviously didn't believe him, so he came to confirm. From this, he could see that his cousin was really good to him and cared about him.

At this time, Wu Han packed up his schoolbag and walked out, waving to Liu Xiaochuan: "Goodbye, teacher!"

"Okay, see you the day after tomorrow!" He said goodbye to Wu Han and then said to Zhao Lijun: "Brother, stop standing at the door and come in and take a look."

Zhao Lijun waved his hands quickly. He was not interested in the place where he was studying. He scratched his head and said, "I just wanted to see you. It's okay. I'm going back. By the way, don't eat out at night. Go back to the hotel to eat! Okay, no need." See you off, I'm leaving!" He said and quickly went downstairs.

On the way back, Zhao Lijun rode his bicycle very fast, and finally felt relieved, "Ogawa, this kid really didn't lie. He is still giving lessons. When we get back, call my aunt Murakami as soon as possible to reassure him."

There was no class in the evening, so Liu Xiaochuan was going back to the Taoliju Hotel for dinner. He couldn't refute his cousin's face. He passed by the small market and bought a fifteen-pound watermelon for two yuan. He also bought a few kilograms of apples and carried them in. to the hotel.

Brother Wang, the boss, was an open-minded person, but the wife didn't say anything on the surface. She was still a little uncomfortable with Liu Xiaochuan coming to eat again. Seeing him come in with fruits, the discomfort was immediately forgotten and she said: "This kid is so polite, why do you want to buy some fruit?"

"Brother Wang, sister-in-law, isn't it a hot day? Why don't we buy some watermelon to quench our thirst?" He said and handed the fruit to the landlady.

Zhao Lijun said in his heart: "This Xiaochuan was very bad last year. He lost a lot of money in a fight at school. But this year he is much more sensible. He can find a job by himself and get into trouble. He has become a completely different person."
